Description

The condition warning system, control system and the method that are used for pot dish cleaning machine
The cross reference of related application
This applies for requiring according to 35U.S.C.119 (e) priority of co-pending U.S. Provisional Patent Application series number of submitting on October 5th, 2,008 61/102866 and the co-pending U.S. Provisional Patent Application series number of submitting on February 4th, 2,009 61/149909, and the integral body with them is incorporated into this by reference.
Technical field
The present invention relates to be used for condition warning system, control system and the control method of pot dish (pot and pan) cleaning machine.
Background technology
A pot dish cleaning machine that is used for the type of restaurant, mechanism and other eating and drinking establishment is usually directed to big rinse bath or pond, and water circulate in this groove or pond to provide the rolling cleaning that pot dish and other " vessel " (i.e. pot, dish, utensil, flatware/silverware etc.) are carried out continuous motion to move.Described a kind of pot dish cleaning machine of this continuous motion style in the laid-open U.S. Patents such as Cantrell numbers 4773436, by reference it has been incorporated in full in this.The machine of Cantrell comprises rinse bath, and this rinse bath has in the position of raising along the even isolated a plurality of nozzles of the rear wall of rinse bath.Be equipped with in the groove to the water of the horizontal plane more than the position of nozzle.Pot dish is put into rinse bath, and activate scavenging pump with drawing-off water from rinse bath and guide water by nozzle to produce injection stream.Its injection stream of each nozzle guide is towards the diapire of rinse bath, then diapire with jet deflection upwards and towards the antetheca of groove.So antetheca makes the jet deflection that the moves up rear wall towards groove, and rear wall deflects down injection stream and along diapire back towards antetheca.Injection stream provides the rolling in the rinse bath to clean action from the combination of the deflection of diapire, antetheca and rear wall.Typically, in the clean cycle of machine, it is continuous roll cleaning action, and unloading vessel when being loaded vessel and thought that vessel are clean during clean cycle by the operator of machine.In this way, during single clean cycle, clean a plurality of vessel loads.
Though disclosed prior art pot dish cleaning machine provides superior cleaning action in the U.S. Patent number 4773436, many parts discussed above have hindered the total efficient and the performance of machine.Invention disclosed provides the total efficient that improved machine greatly and the parts of performance in the U. S. application series number 09/947484,09/947485 and 10/744666, comprise improvement to introducing and delivery pipe, nozzle, pump and system assembles method, open in this integral body of having incorporated U. S. application series number 09/947484,09/947485 and 10/744666 by reference into.Yet the machine of these improvement and U.S. Patent number 4773436 is all less than many shortcomings of handling the typical condition warning system, control system and the control method that are used for this machine.
The classical control system and the control method that are used for the pot dish cleaning machine of continuous motion type comprise that typically the restriction clean cycle is in the control logic of predetermined running time.In case predetermined running goes by, with regard to the operation of forbidden energy scavenging pump, and rinse bath that must the emptying machine and before can beginning another clean cycle, refill this rinse bath.This guarantees that washing fluid solution in the rinse bath is discharged from usually and the dirt level in fluid refills washing fluid solution before significantly and unfriendly influencing the cleaning performance of the fluid in the cleaning machine.In many application, be that expectation refills the rinse bath enough circular flow time before the running time of finding four (4) hours.Yet, should be appreciated that the desired predetermined running time of some different factor affecting to application-specific.Also have, in some cases, before predetermined running went by, clean cycle was terminated too early.For example, in some machines, in control system, comprise safety shut off switches (kill switch), when surpassing predetermined safety operation temperature, close whole system with the fluid temperature (F.T.) in rinse bath.In this case, no matter running time of passing, essential emptying also refills rinse bath, and before cleaning machine is operated once more the new clean cycle of essential startup.
Though classical control system discussed above and method provide benefit aspect the condition for validity of the washing fluid solution in guaranteeing safety and/or rinse bath really, but need to have started new loop limit will identical or similar control system or method be used to strengthen the ability that is consistent with the machine operation condition of many expectations, these conditions not affected temperature of safety and/or washing fluid dirt level are so important (such as preferably cleaning, rinsing or fluids for sterilization operating temperature; Preferably cleaning, rinsing or disinfectant groove/supply operating fluid horizontal plane; Preferably cleaning, rinsing or fluids for sterilization operating chemical product concentration level; Chemicals level of supply, pressure or concentration; Deng).Therefore, provide and to help to guarantee or strengthen being consistent and the control system and the method that do not need to reset clean cycle and/or drain and refill rinse bath are useful with this operating condition.
In addition, often cause difficulty Yu Ding running time towards wash cycle.Because vessel are loaded and unloaded in whole clean cycle, nearly the vessel that load during wash cycle may not become enough clean before clean cycle is finished.Thereby, must drain and refill rinse bath and start new clean cycle and clean those vessel to finish.If equipment be turn-off to close by day, then to refill rinse bath be very consuming time and the waste resource.This problem is also by following true the increase: conventional cleaning machine do not provide the operator about any indication of running time of passing or advise of same was provided before finishing clean cycle in advance.Thereby unless when operator's record starts clean cycle, otherwise the operator determines that when clean cycle is finished is impossible.Provide during therefore, in the end of clean cycle or towards the end of clean cycle and allow that the operator fully cleans vessel and the control system and the method that need not to start new clean cycle will be useful.
The classical control system and the control method that are used for the pot dish cleaning machine of continuous motion type typically comprise single standard/normal clean cycle, and this limits clean cycle in the predetermined running time in mode discussed above.In some machines, after clean cycle was finished, control system kept fluid temperature (F.T.) minimum or predetermined in the rinse bath, soaked effect to improve.This makes it possible to realize cleaning model whole night, wherein the vessel of heavily contaminated can during whole clean cycle, be placed in the rinse bath and be cleaned and after clean cycle is finished before article are removed morning at night all the other times additionally soaked.Though this provides the ability of cleaning the heavily contaminated article really, when article are removed, fluid often no longer is emulsification, and dirt condenses on the flow surface and even is attached to vessel again.Thereby, often need additional or unnecessary cleaning.Thereby it is useful that the control system and the method for the cleaning that improves cleaning machine counterweight contaminated articles are provided.
The classical control system and the control method that are used for the pot dish cleaning machine of continuous motion type, and be used for wherein operating, the monitored miscellaneous equipment of safety or adaptability parameter (includes but not limited to kitchen appliance, automat for manufacturing, milling machine, transfer system, condition monitoring instrument etc.) those system and methods typically utilize the condition warning system, this warning system or need operator's (being defined as control or anyone of watch-dog widely) in this closely monitoring directly be in the display or the control panel of operator front, loud noise alarm or the direct video alarm in operator's sight line perhaps are provided.Except that the operator of apartment warning, audio alert and sight line video alarm signal are also often warned near other people roughly, and concerning these people, this alarm or signal are undesired and often are not expect to exchange.Particularly, at the restaurant, the experience of having a dinner that loud audio frequency buzzer and/or sight line vision signal are often disperseed the consumer, and also can be appointed various different tasks and all use at quilt and cause among the employee of similar alarm method and obscure and/or setback.Therefore, provide that not need the tight display of operator or control panel and minimize the condition warning system that transmits alarm signal to recipient that do not expect and/or inappropriate simultaneously be useful.
